. QE'ECIFICATION forming part of Letters Patent No. 455,926, dated July 14, 1891 Application filed April 20, 1891. serial No. 389,548. (No model.) I

* in the county of Essex and State of New J ersey, have. invented certain new and useful Improv'ments'in Drain-Pipes; and I do hereby declare the following. to be a full, clear, and exact description of the invention, such as will enable others Skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked there on, which form a part of this specification.

This invention relates to improvements in drain-pipes; and it consists in the features of construction illustrated in the several figures of the accompanying drawings, which features are fully set forth in the following specification and more fully pointed out in the claims appended thereto.

The purpose of the invention is to provide a drain-pipe which is. of simple and strong construction, each drain-pipe section being provided with an attached collar and a fiat bottom or base, whereby the sections comprising the line of drain-pipe can be more readily placed in position and secured together with comparatively little labor.

The invention is applicable more especially on that class of pipe-sections which are oval or egg-shaped in cross-section and which without my improvement are very diificult to set in position, owing to the narrow surface at the in cross-section.

In the accompanying sheet of drawings, in which similar letters of reference are employed to indicate corresponding parts in each of the views, Figure 1 is a side. elevation of one of my improved drain-pipe'section's, which is of the oval or egg-shape type. Fig. 2 is an end View of the same, looking in the direction of arrow Fig. 3 is an end view of the pipe-section, looking in the direction of arrow as"; and Fig.4: is a vertical section of the pipesection taken on line a: in Fig. 1 and looking in the direction of arrow 41;. Fig. 5 is a vertical section of a pipe circularin cross;sec-' tion, provided with the fiat bottom or base;

and Fig. 6 is an end view of the collar end ofa round or circular pipe.

Drain-pipes of this class to which my improvement appertains as heretofore made were either circular, oval, or egg-shape in cross-section, were provided with a flat bottom or base, which base is of the sameor greater thickness than the collar for cementing the pipes togetherr By thus providing each section of pipe with a' fiat base which is readily handled and placed in position by the workman and can be manufactured at less expense than the drain-pipes provided with flat bases as heretofore made.

By my improvement each section of pipe is provided with a flat bottom or base, whereby the workman can very quickly set the sections and cement them together without first propping them up, as heretofore. In the drawings is illustrated the means which I have devised to accomplish this result.

In said drawings, A indicates a drain-pipc section, preferably made of terra-cotta or vitrified clay, which may be oval or egg shaped in cross-section, as indicated in Figs. 2, 3, and 4, or it may be round or circular in cross-section, as indicated in Figs.5 and 6. On aline with the lower edge a of the body of the pipe, projecting on opposite sides thereof and extending in the longitudinal direction of the pipe, I have formed said pipe with the outwardly-extending portions 1) Z), which are formed integral with the pipe inthe molding of the same, and which parts form a flat bottom or base 11 to the section of pipe.

From Fig. 1 it will be seen that each pipesection A is provided with the usual attached collar 0 for the reception of the end of the 9 next section of pipe, and said parts I) 1), forming the base b extend longitudinally back on opposite sides of the lower edge a to nearthe other end of the section, terminating at b at a distance from v the edge of the pipe-section equal to the depth of the collar on the next section of pipe, so that the end a of the pipe can be placed in said collar and the two sections of pipe securely cemented together.

The particular advantage gained by providing the pipes with a flat bottom is that a perfectly level trench can be dug for the pipes, digging away only a small hole or trench for the reception of the bottom of the collar 0. Therefore in the oval or egg-shaped pipes as thus constructed there is no need of propping them up in order to prevent them from falling over, and the drain-pipe can be set in. place in much less time and with less labor and less expense.

Having thus described myinvention, what I claim isl. A drain-pipe section, of terra-cotta or vitrified clay or other suitable plastic material,

provided with a collar, and a flat bottom or base extending longitudinally back from said collar and the lower portion of said collar projecting below said base, as and for the purposes set forth.

2. Adrain-pipe section, of terra-cotta or vitrified clay or other suitable plastic material,

provided with a collar and parts I) 1), projecting on opposite sides of the lower edge and formed integral with the body of the pipe, said parts extendinglongitudinally back from said collar, thereby forming a flat bottom or base, and the lower portion of said collar projecting below said base, as and for the pur poses set forth.

8. The herein-described oval or egg-shape drain-pipe section, consisting of the pipe portion A, with a collar 0 attached, and a fiat loottom or base 19 at its narrowest portion and the lower portion of said collar projecting below said flat base, substantially as and for the purposes set forth.

4. The herein-described o'val or egg-shape drain-pipe section, consisting of the pipe portion A, with a collar 0 attached, and oppositely-projecting portions 1') b, forming a fiat base b said portions extending longitudinally from said collar to near the end a of the pipe and terminating at b to permit the insertion of the pipe into, the collar on the next section, and the lower portion of said collar projecting below said base, substantially as 1 and for the purposes set forth.

In testimony that I claim the invention set forth above I have hereunto set my hand this 17th day of April, 1891.
